Kaeng Krachan National Park was established in 1981 AD on an area of 2,914 square kilometers. It is the largest national park in Thailand, and is considered one of the favorite destinations for many locals and foreigners alike. This is because of its forests, waterfalls and amazing landscapes (you can camp near them), in addition to being home to leopards, tigers, bears, macaques, deer, elephants and other wild species.
